This page presents some articles that I've made.

Analysing The GT2 & DRP1 - active filter sections rel. 18/1 2005 This document shows the result of my PSpice simulations of the final filter sections of both the Sansamp GT2 and the Marshall DRP1. The simulations are in frequency domain.

Analysing The Guv'nor - gain stages released 15/7 2004 This document shows the result of my PSpice simulations of the 2 gain stages used in the good old Black Series Marshall stomp box. The simulations are in frequency domain.
